Unit 11 volume & surface area homework 5 surface area of prisms & cylinders
likoan [24]

The volume of the prism is the amount of space on the prism

The volume of the cylinder is 760 cubic units

<h3>How to determine the volume?</h3>

The question is incomplete.

So, we make use of the following parameters

  1. Shape = Cylinder
  2. Radius, r = 11
  3. Height, h = 2.

The volume of a cylinder is calculated using:

V = πr²h

Substitute known values in the above formula

V = 3.14 * 11² * 2

Evaluate the product

V = 759.88

Approximate

V = 760

Using the assumed values, the volume of the cylinder is 760 cubic units
